@sjxoxo There will plenty of kindness but also plenty of expectations. It will be expected that a baby will settle on his own, that at meals time, baby will use the fork and eat whatever is offered with minimal assistance, well maybe not at 9 months.
A lot of parents use nounou, the nanny, often shared.
A PP is right, going only 2.5 days might make it harder. Also, it will be harder if there is a great difference between home and nursery. For example meals. Not only what you eat but how you eat it as well. You will never see in a French café a group of mums and babies leaving the mess they do in UK or Australia (where I am based now) or even fussy eaters.
There will be very little tolerance from the staff about children's individual peculiarities such as like / dislikes, sensory difficulties, ....
It is more likely you will receive " homework" and be told he need to learn this or that at home, for things such as using a fork, washing hands, listening. Which when you move to school, will become, working on some reading or arithmetic.
Kids however become very resilient, and independent. They will be praised for what deserve praising not for every single action they take all day long .
You not talking much French will not make it easier. Do you work and need to send him , or can you wait a bit. If you have to send him, maybe increase the day, and use the extra hours to accelerate your learning of French.
